Using PathView.view in a binding of an ObjectModel delegate produces null warning

Using PathView.view in binding produces cannot read property 'count' of null warning, where the binding doesn't recover. In Component.onCompleted phase the attached property is already available:
import QtQuick 2.0
import QtQml.Models 2.1

Rectangle {
    id: root
    property int itemWidth: width
    property int itemHeight: height * 0.8
    width: 200
    height: 400
    PathView {
        anchors.fill: parent
        pathItemCount: 3
        path: Path {
            startX: itemWidth/2; startY: -itemHeight + (root.height - itemHeight)/2
            PathLine { x: itemWidth/2; y: 2*itemHeight + (root.height - itemHeight)/2 }
        }
        preferredHighlightBegin: 0.5; preferredHighlightEnd: 0.5
        highlight: Item {}
        model: ObjectModel {
            Item {
                property int index: ObjectModel.index
                property int count: PathView.view.count
                Component.onCompleted: console.log("PathView", ObjectModel.index, PathView.view.count, PathView.currentIndex)
                width: itemWidth
                height: itemHeight
                Text {
                    anchors.centerIn: parent
                    text: (parent.index + 1) + "/" + parent.count
                }
            }
            Item {
                property int index: ObjectModel.index
                property int count: PathView.view.count
                Component.onCompleted: console.log("PathView", ObjectModel.index, PathView.view.count, PathView.currentIndex)
                width: itemWidth
                height: itemHeight
                Text {
                    anchors.centerIn: parent
                    text: (parent.index + 1) + "/" + parent.count
                }
            }
            Item {
                property int index: ObjectModel.index
                property int count: PathView.view.count
                width: itemWidth
                height: itemHeight
                Text {
                    anchors.centerIn: parent
                    text: (parent.index + 1) + "/" + parent.count
                }
            }
            Item {
                property int index: ObjectModel.index
                property int count: PathView.view.count
                width: itemWidth
                height: itemHeight
                Text {
                    anchors.centerIn: parent
                    text: (parent.index + 1) + "/" + parent.count
                }
            }
            Item {
                property int index: ObjectModel.index
                property int count: PathView.view.count
                width: itemWidth
                height: itemHeight
                Text {
                    anchors.centerIn: parent
                    text: (parent.index + 1) + "/" + parent.count
                }
            }
        }
    }
}
In general it seems ObjectModel and PathView don't play along nicely, e.g. saw one ObjectModel delegate not getting reference to PathView.view at all (but other identical delegates did), unfortunately failed to produce simplified examples to reproduce to write a bug about it.
